Re: searched and searched with no results, any instructions on installing Mark's exha
Ron,
I installed a set of Marks Pipes a few months ago. Just lay all the parts on a blanket or cardboard so you can get a look at them. It is self explanatory as far as which pipes go where. If I remember right I started by putting the head pipes onto the two rear cylinders first. Don't tighten the flanges up too much yet. I then put one of the headpipes onto a front cylinder and left the bolts pretty loose. Then, went under the bike and put a the collector on the side with both front and rear pipes. Then put the collector on the other side, other front head pipe, and wiggled everything together. You gotta leave the flange bolts loose to you get everything in there. Once all the pipes were in place I snugged the bolts a bit more but not enough to lock it all in place, just somewhat tight. Then pushed all the joints together as tightly as they would go. Then, put on the mufflers. Once the mufflers were on and I saw it was all lined up OK then I gave everything the final torque. Don't be surprised if you need to adjust things to make the mufflers look right. Mine both needed some "precision" alignment. I did this by grabbing the can and rotating it away from the frame in effect bending the mounting tab VERY SLIGHTLY. Otherwise the muffler can would have been touching my shock on one side.
My exhaust gaskets were fine, no need for new ones on my bike. I did not apply any sealant to the exhaust joints. I debated but Mark said he did not feel it to be necessary and it hasn't leaked yet so I guess its good. You may need new bolts to mount the mufflers to the bike. Mark will give you two nuts to use with the stock bolts, but I found the bolts to be a bit too short for my liking. The stock bolt is 10mm x1.25 thread. I don't remember the length though. I purchased some button head stainless bolts that are 10 mm x 1.5 thread x 60 mm long and also had to buy two new nuts for the bolts since the thread pitch was different. I had a hard time finding anything 10mm x 1.25pitch.
See attached for torque values on flange bolts and muffler bolts.
Oh, and I had to make a tool to tighten the flange bolts on the rear head pipes. it was an allen key cut down to about 1" or so. I had to turn the little nub with a wrench. That was only on the two bolt on the inboard side of the rear cylinders. The rest of them were easily reached with a typical ratchet drive allen socket.
